Right now the way environments are duplicated requires named gym environments. For third party gym environments without names, or supersuit wrapped gym environments, this doesn't function. The typical way to duplication in these cases is pickle or cloud pickle, and there's a few things we'd like to use this for that pickle can't handle. Also, gym depends on cloud pickle, so this isn't really adding a new dependency.
